      🎉 Successfully added {{ groups['linode_all'] | default([]) | length }} Linode hosts to inventory!
      
      📋 Hosts discovered:

      - {{ host }} ({{ hostvars[host]['ansible_host'] }})

      📂 Groups available for targeting:
      {% for group in groups.keys() | sort if group.startswith(('tag_', 'region_', 'type_', 'status_')) %}
      - {{ group }}: {{ groups[group] | length }} hosts
      {% endfor %}
      
      💡 Use these groups in your job templates:
      - tag_k3s: All k3s cluster nodes
      - tag_control_plane: Control plane nodes only  
      - tag_worker_node: Worker nodes only
      - region_us_southeast: All hosts in us-southeast
      
      ✅ Hosts are now available for subsequent job templates in this workflow!
